building management system

Building Management Systems are most commonly implemented in large projects with
extensive mechanical, HVAC, electrical, and plumbing systems.BMS controlling the
building's internal environment, BMS systems are sometimes linked to access
control (turnstiles and access doors controlling who is allowed access and
egress to the building) or other security systems such as closed-circuit
television (CCTV) and motion detectors. Fire alarm systems and elevators are
also sometimes linked to a BMS, for monitoring. In case a fire is detected then
only the fire alarm panel could shut off dampers in the ventilation system to
stop smoke spreading and send all the elevators to the ground floor and park
them to prevent people from using them.
